Oclyte® Streetlight Column

Electricity undergrounding has led to increasing demand for an aesthetically pleasing column for street lighting in both residential and commercial areas. The Oclyte® column provides an extremely versatile combination of mounting heights, base types and outreach shapes to satisfy the requirements of the asset owner.

Oclyte® modular steel columns comprise a range of interchangeable octagonal tapered steel elements each of which friction fit together to provide the desired height between 3 and 13m. These steel galvanised octagonal sectional columns come in a number of mounting heights and installation options to suit any street lighting requirements.



The columns are manufactured from mild steel with a minimum yield of 250 MPa ranging in thickness from 2, 3 and 4mm, which, after folding, is seam welded and then hot dip galvanised to finish. Higher yield steels are also used where high loads and taper constraints dictate.



The Oclyte® columns are computer designed, based on the sail area for the particular wind speed at the installation, to the following Standards:

  • NZS 3404: 2009 - New Zealand Structural Steel Design Standard (includes fabrication)
  • AS/NZS 4680: 2006 - Hot Dip Galvanised (Zinc) Coatings on Fabricated Ferrous Articles
  • AS/NZS 4600: 2018 - Cold-formed Steel Structures Design Standard
  • AS/NZS 1170: 2011 - Structural Design Actions
  • AS/NZS 4676: 2010 - Steel Utility Services Poles

The octagonal sections are generally 3.6 metres in length with half-sections used where necessary to provide a full range of mounting heights. They are enumerated from section '0' at the top, to section '7' at the base. The poles have an approximate taper of 21mm per metre.
